[Surreal17]

Beside all the messages and images that ayu is trying to convey with this album, she's also portraying a fierce woman with a sexy & provocative image.
For reference, we have the Sparkle PV + Lyrics ("Let your body feel it/ Be bolder
To the point of shamelessness /You'll never know unless you touch") , GREEN PV (that sensual dancing with the woman and all those provocative hey-I'm-watching-you scenes), identity from Arena Tour 2009 (ayu is flirting with SHU-YA), also LOVE'n'HATE from Arena Tour 2009 (ayu surrounded by men, even if she mostly has a rejection attitude) and even Rule PV (ayu's moves, clothes and her overall look). Load of the SHUGYO Special Screen from AT 2009 can also be interpreted as being sexual with all those men being held hostages by some women, with ayu trying to help them escape.
Let's not forget about the booklet ( e.g. Dis-comunication page reminds me of Sparkle PV with the tight costume & violet shiny cap ayu's wearing, and also her position) which again shows ayu in a sexy mood.

So, looking from this angle, NEXT LEVEL may signify ayu's change towards a more sexualised image (although she started using elements since 1999).
